These improvements, which are due mainly to a rise in efficiency, produce locational advantagesand increase the attractiveness of these cities, thereby possibly enhancing their competitivenessand economic growth. However, there may be equity issues at stake, as the main accessibility benefits are primarily concentrated in urban areas with a HSR station, whereas other locations obtain only limited benefits. HSR extensions may contribute to an increase in spatial imbalance and lead to more polarized patterns of spatial development. Procedures for assessing the spatial impacts of HSR must therefore follow a twofold approach which addresses issues of both efficiency and equity. This analysis can be made by jointly assessing both the magnitude and distribution of the accessibility improvements deriving from a HSR project. This paper describes an assessment methodology for HSR projects which follows this twofold approach. The procedure uses spatial impact analysis techniques and is based on the computation of accessibility indicators, supported by a Geographical Information System (GIS). Efficiency impacts are assessed in terms of the improvements in accessibility resulting from the HSR project, with a focus on major urban areas; and spatial equity implications are derived from changes in the distribution of accessibility values among these urban agglomerations. date: 2013-02 date_type: published publisher: Elsevier official_url: http://www.sciencedirect.com/science/article/pii/S0264275111001314# id_number: 10.1016/j.cities.2011.11.002 full_text_status: public publication: Cities volume: 30 pagerange: 18-30 institution: Caminos department: Ingenieria_Civil8 refereed: TRUE issn: 0264-2751 rights: by-nc-nd citation: Monzón de Cáceres, Andrés and Ortega Pérez, Emilio and López Suárez, Elena (2013).
